Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542642, here are decompositions:

43 + 542599 = 542642
103 + 542539 = 542642
109 + 542533 = 542642
181 + 542461 = 542642
241 + 542401 = 542642
271 + 542371 = 542642
349 + 542293 = 542642
379 + 542263 = 542642

Showing the first eight; more decompositions exist.
